Default Re: KEL84 clicks and pops from right channel?

Hi Dave,

Well, clicks and pops sounds like it could be interference so worth bearing in mind if you can tie that up with light switches or thermostats switching.

Check the faq,
http://www.world-designs.co.uk/forum...read.php?t=135
for the small valve anode resistors R10, 11, 12, 13. I had that problem of anode resistors breaking down and it starts as rustling and popping so change them first if you didn't already do it.

Past that, more soldering of all the joints on the R channel. Then component-wise the cathode bypass caps, C6,7, 12. 13, 14, 15 would be next for me.
